Good design but

So the creature design is pretty good, but the one weakness of both your submissions is that we have no sense of how the thing might move. You can put a creature in poses and in contexts such that the audience will "see" how it moves and what's about to happen within an image. This pose doesn't do that. This is sort of the "statue" pose, like a human standing straight with arms outstretched. To really make the creature stand out, it needs to feel alive i.e. moving.

Also, I love the background "ice", but it doesn't look like ice. I wish you had made it green-tinged and called a kryptonite cave, or maybe made it read and called it a crystalline-lava cave ... but ice? Ice is either transparent with microcracks, or it is white with a highly grainy (read: not crystalline) surface.

You're so close to delivering a fantastic piece, but there's little mechanistic things standing in its way at the moment.
